Analyze your cells in Real Time

Live cell analysis with xCELLigence® – much more than an endpoint assay can deliver.

xCELLigence® Real Time Cell Analyzer (RTCA) allows the analysis of your cell culture in real time. A huge variety of cell-based assays, such as proliferation, adhesion, cytotoxicity, migration, morphological changes and more can be performed (for detailed information please visit our download section). Furthermore, xCELLigence® is scalable. Depending on your throughput, evaluate 16 up to 4 x 384 well-plates simultaneously.

Live Cell Analysis with xCELLigence

Highly Sensitive: The impedance-based technology is highly sensitive, allowing very low effector to target ratios. Continuous cell monitoring in real time enables investigation of short- and long-term effects. As a result, a full kinetic read out of the cellular behaviour is obtained- objective and quantitative.

Non-Invasive: xCELLigence® requires no cell labeling, which increases the physiological relevance and reduces the workload.

Easy to operate: Now run your cell-based assays with xCELLigence® RTCA easily. Literally! Click on RUN button and RELAX.

How does it work?

xCELLigence® technology is based on impedance sensing. The E-Plates® form the heart for this technology.  The functional unit of the E-Plates® are the gold microelectrodes, which cover 70 – 80 % of its well-bottom area (Figure 1).

C) Zoomed-in photograph of gold microeletrodes on the E-Plate® well bottom. D) Unstained human cells, growing on microelectrodes

For impedance measurement, a very low electric current is applied to the plates, flowing through an electrically conductive solution (cell culture media) from one microelectrode to the other (Figure 2A). As soon as cells adhere to these microelectrodes they act as electrical insulators, thereby influencing the impedance signal (Figure 2B). Importantly, cell behaviour is not affected by the gold microelectrodes or the electrical current which is applied.

How does the analysis look like?

The change in impedance is reported as a dimensionless parameter called Cell Index (CI, CI= impedance at time point n – impedance without cells/nominal impedance value).

Figure 3 shows a typical course of the CI value during an apoptosis assay. Directly after cell seeding, cells start to adhere, thereby inducing a rapid increase of the CI value. The adhesion phase is followed by a phase where cells grow exponentially, indicated by a continuous increase of the CI value. When cells are confluent the CI value cannot further increase, thus forming a plateau. Upon the induction of apoptosis by a certain treatment cells start to die and subsequently detach from the well bottom. The reduction of adherend cells is reflected by a decrease in the CI value.

Investigate a huge variety of cell-based questions

Cellular impedance is influenced by many factors, like strength of adhesion, cell number, cell morphology and cell-cell-contacts.

xCELLigence RTCA Family

Depending on your throughput different xCELLigence® RTCA systems are available.


RTCA S16
With one single 16-well plate the S16 is the smallest member of the xCELLigence® RTCA family. It is the pefect device for assay development and optimization.


RTCA DP (Cell Invasion and Migration)
Highest flexibility: Three 16-well plates can be operated seperatly or together, giving you the possibility to run 48 wells in parallel to maximize productivity.
Migration and Invasion: Besides the „normal“ E-Plates®, the DP system can be operated with CIM (Cell Invasion and Migration) Plates® to investigate migration and invasion of cells.

RTCA SP (Single Plate)
In the SP (Single Plate) model one 96-well plate can be analyzed. In approximately only 7 seconds the whole 96 well plate is measured.

RTCA MP (Multi-Plate)
The MP system offers the opportunity to analyse from one up to six 96-well plates. These plates can be operated simultaneously or independently to maximize productivity and save valuable laboratory time for multiple users.

RTCA HT (High Throughput)
The HT system allows high troughput analysis of a 384-well plate. To maximize the throughput, up to four instruments can be integrated and monitored by one control unit. This gives you a maximal screening capacity of 1536 wells in total.

The eSight is the first system of its kind that combines high sensitivity of xCELLigence impedance-based measurement with the benefit of live cell imaging. These two modes can be evaluated simultaneously, providing an extraordinary insight in cellular behaviour and underlying mechanisms. Analyze up to five 96-well plates in parallel or individually – in real time, using bright field or up to three colours (green, blue, red).


RTCA Cardio (Cardiomyocyte Contractility)
Analyze cardiomyocyte contractility and viability in real time. Similar to the other RTCA xCELLigence® members, the Cardio system is based on noninvasive measurement of electrical imedance to monitor changes in cellular morphology, proliferation and attachment.
The difference to the other RTCA systems is a higher aquisition rate of 12.9 milliseconds. This high aquisition rate in the range of milliseconds enables the detection of morphological changes that are due to cardiomyocyte contractility. The cycle of cardiomyocyte contraction and relaxion is recorded as a rhythmic chance in cellular impedance.
Furthermore, the Cardio model allows investigation of cell viability. This facilitates short- (second) and long- (days) term investigation of cardiotoxicity which becomes highly relevant for clinical safety testing.
The Cardio system can be used to study stem cell-derived, induced pluripotent stem cell (iPSC)-derived, or primary cardiomyocytes.
Cells are analyzed in a 96-well format.

RTCA Cardio ECR (Cardiomyocate Contractility and Electrical Activity)
Analyze cardiomyocyte contractility, viability and electrophysiology in one run.
Similar to the Cardio model, the Cardio ECR system has a second measurement mode within the millisecond range that enables the detection of cardiomyocyte contractility.
As additional benefit, the Cardio ECR (ExtraCellularRecording) model is equipped with an enhanced acquisition rate of 1 millisecond. Furthermore, it is able to measure the extracellular field potential at 10 kHz and to perform cardiomyocyte pacing. This pacing function supports the development of functionally mature cardiomyocytes.
These extra functiosn of the Cardio ECR model provide an unpredicted deep insight into cardiomyocyte health, cellular responses and underlying mechanisms to certain drugs. Therefore, xCELLigence Cardio ERC system is of relevance for any kind of in vitro assays, investigating drug induced cardic liability.


RTCA ePacer (Cardiomyocyte pacing)
The ePacer is the system of choice to produce functionally mature hiPSC cardiomyocytes in an easy and efficiant way.
Less cell stress: Precise and standardized pacing conditions result in improved maturation of hiPSC cardiomyocytes in only 2-3 weeks. From just a few wells up to six 48- or 96- well E-Plates® you can analyze cardiomyocyte beating pattern.
Integrate the ePacer into your existing workflow: Combine the ePacer with your existing readouts, such as calcium measurements, microscopy, voltage sensitive dyes or plate readers.
Furthermore, investigate contractile and electrical responses of long-term paced hiPSC cardiomyocytes with the xCELLigence RTCA CardioECR system. Contractile responses only can be explored using the xCELLigence RTCA Cardio system.

AccuWound® 96
Investigate Cell Migration and Invasion in an incredible easy and highly reproducible manner.
AccuWound®96 automatically produces 96 identical scratches in a 96 microtiter plate. Unlike in traditional scratch assays / wound healing assays, these scratches are highly precice with a coefficent of variation of around 4 % compared to 20% which is typical for traditional scratch assays.
In combination with xCELLigence RTCA systems, cell migration/ invasion can be investigated in real time. Giving you precise and objective insight into the full kinetic of scratch closure.

We are studying oncogenic and metastatic signaling pathways in pancreatic carcinoma cells. Cell migration assays using the xCELLigence DP system have proven indispensable for our work, as it allows us to generate valuable, easily quantifiable kinetic data, combined with a simple and time-saving setup procedure.
